Table 1 Tissue sample number, region of provenance and prevalence using liquid media technique

From: Molecular identification of Mycobacterium bovis from cattle and human host in Mali: expanded genetic diversity

Sample provenance Number of examined cattle Number of cattle with lesions Percentage of cattle with lesion Number of positive M. bovis Percentage of positive (microscopy) Percentage of positive (liquid media culture)
Kayes 75 11 14.7 % 1 1/11 (9.1 %) 1/11 (9.1 %)
Sikasso 160 12 7.5 % 4 4/12 (33.3 %) 4/12 (33.3 %)
Ségou 80 10 12.5 % 1 0/10 (0 %) 1/10 (10 %)
Mopti 140 19 13.6 % 5 4/19 (21.55) 5/19 (26.3 %)
Bamako 220 27 12.3 % 8 7/27 (25.9 %) 8/27 (29.6 %)
Total 675 79 11.70 19 16/79 (20.25 %) 19/79 (24.05 %)
  1. Among the 675 cattle screened, 79 have presented lesions leading to a rate of 11.70 %. The regions of Kayes and Mopti have presented the highest rate of lesions respectively 14.7 % and 13.6 %. In contrast, Sikasso has the lower rate with 7.5 %. The general prevalence of the infection was 2.81 % with the highest prevalence in Bamako (8/675) with 1.18 % and the lowest was observed in Kayes and Sikasso (1/675) with 0.15 %. Tests performed on the 79 lesions obtained, the number of infected lesions with M. bovis observed was higher in Sikasso, Bamako and Mopti with respectively 33.3, 29.6 and 26.3 %. This table shows that 34.2 % of cattle were investigated in Bamako followed by Mopti with 24.1 % and Ségou has the lowest number of cattle 12.6 %. This was no statistically significant difference between the number of specimens collected in each site (p = 0.47)
